Dunno, but one thing's for sure.
It'll be Demon's respnsibility to get it sorted.

I'm not in complete agreement with this although UK and European
Providers are generally very poor in their specification.
With regards to US upgrades, from what I hear, MCI are starting to lay
the new OC3 as part of their network. This is a 9.6Gbit/s fibre
connection that should give the US networks the opportunity to
interconnect thorugh a very fast backbone that will allow for some
growth.
We will not be seing this over here for a while because current UK to
US cabling does not have the spare capacity to support such links. New
cabling would take years to lay and the cost of this puts it well
beyond the reach of any UK or European ISP.

Mike, I have a direct T1 link to sprint in the US at work,
and Demon at home. Let me tell you that the bottleneck is
CERTAINLY NOT IN THE US !!! Sure, certain sites
are congested, but take Microsoft as a reference site,
via work (over 28K modem back home), www pages come
up very quickly. Access the same pages via demon, a few
minutes later, forget it !

I guess the answer is that transatlantic cabling is very, very expensive to
install and maintain. There's not just the cost of laying undersea fibres
(satellite links are really a non-starter as far as getting decent response
times are concerned), there's the maintenance. After all, what do you do
when a cable gets broken in fifteen billion fathoms (well, OK, not quite
that much) of midatlantic seawater? It's not just a case of sending a bod
down a manhole with a splicing kit...
And _then_ there are the profit margins.. I'm hardly surprised that it's as
expensive as it is. Maybe as fibre capacities get increased things'll get a
little cheaper, but with the world demand for telecomms services rising like
it is demand will probably dictate pricing again. Sad but true.. well,
probably true. This is just idle speculation.
Anyhow, FCI have probably cracked it. They've got SIXTEEN BILLION MILLION
TRILLION TERABITS/SEC of transatlantic bandwidth. *grin* [1]

I heard that they use a proprietary secret technique that uses sea
water as the transmission medium<g>.
We're presently investigating a method of using carrier-planctum for
the high-volume transit of traffic. We have a pipe about as wide as
the length of UK with dispatchers stationed at strategic points along
the coast to send and collect this data. The information, 1 bit per
planctum washed ashore, is then sent to Swansea where our data
re-assembly point makes sense of the random individual bits of data.
We estimate we can send about 10terabits at any one point, but at
present cannot make any guarantees about how long it takes to get to
the destination. Furthermore, we haven't been able to find a way to
make the data reappear as it was sent. If we use checksumming, we end
up having to throw away 99% of the data, so a decsion was made to
accept losses as a casualty of transit.

The plankton density ratio for any given point never exceeds the 10.3
required for the tunnel effect. As this point, there is enough
strength to hold up enough medium for said tunnel. As for the routing
of IP traffic over the Internation Plankton eXchange (IPX), it remains
to be seen if the RTT/MRU-MMU-LSD-ADT-NCC-NOC parameters offset the
NRI-NBC/BBC+ITN phenomenon.
I particularly like the "ISDN Intensifier"

I think Demon used this technique for email and news some months ago,
but have now abandoned it. I think their new system uses fish instead of
plankton since they keep on about how scaleable it is. Seems more
reliable anyway. Presumably the scales stop the seawater corroding the
data.

You know, you can really do that... Good for a few hundred baud over say 50
meters off 24v supplies. Perfect for scuba diver comms, no multipath
distortion.
Of course, I prefer syncopated Krill. The jaw clicking of a shoal containing
a couple of million Krill acts a decent white noise generator. If you can
train the Krill to click in burst mode you have a binary data transport.

Nynex already have a number of STM-4 rings in Manchester.
9.6Gbps is not alot of bandwidth for a telco -- it is only 16 STM-4, or
32 pairs of fibre.

I use my own handy product, which could be described as an accelerator.
It's called EMpathy. The EMpathy home page can be found at:
<URL:http://www.enrapture.com/cybes/empathy/>.
If anyone would like to try EMpathy on carrier pigeons, please let
me know what kind of increase in bandwidth you get. I've been using
it for the last few years with my modem, and I've got some unbelievable
results. For example, during the recent "troubles" with Demon's news
server, I was still able to connect to it each day and receive news
from it at a reasonable speed. Some may disbelieve it, but I swear
it actually happened. However, I'm not having much success with the
MS news server msnews.microsoft.com, so perhaps EMpathy's compatibility
feature (making compatible with more hardware/software/wetware/limpware
than I can list - _nobody_ knows how long many things work with it!)
needs an upgrade.
For a demo of EMpathy, just take a look at the home page (see above),
as EMpathy automatically installs itself on your hardware/software/etc
just by reading the EMpathy home page. Even your browser may get faster!
Hmmm. I've never tested it with plankton. I wonder...

The scalability factor is the swap from plankton to carp to large salmon to
sharks to whales to the blue whale. At this point we have used all capacity
up and as the food chain says, we go back to plankton !

AH - TinWire (TM) know it well.
We did a project recently with this technology. Works well over short
distances in dry weather, but the rain on the wire tends to confuse the
receivers. Long distances was also a problem, as the wire tended to sag
and beyond a few thousand metres, broke under it's own weight.
The biggest problem we had was that we never managed to work out a way
to scale to three tin cans.

What you need is IBM's latest product in LAN technology, the
